Coleus plant named ‘UF12-82-3’

ABSTRACT

‘UF12-82-3’ is a new coleus plant distinguished by having a combination of novel mounded growth habit, excellent heat tolerance, and lance-shaped leaves consistently colored deep maroon with bright green margins that is significantly different than other coleus plants.

Latin name of the genus and species of the plant claimed: Solenostemon scutellarioides.

Cultivar denomination: ‘UF12-82-3’.

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct cultivar of coleus plant named ‘UF12-82-3’. ‘UF12-82-3’ originated from an open pollination conducted in May-November 2011 in Gainesville, Fla. between the female coleus plant ‘UF11-73-8’ (unpatented) and an unknown male coleus plant. A single seedling was chosen in May 2012 for further asexual propagation in Gainesville, Fla. (see FIG. 1 for pedigree).

‘UF12-82-3’ has been reproduced asexually for over one year through vegetative cuttings and has been found to retain its distinctive characteristics through successive asexual propagations. ‘UF12-82-3’ was first propagated asexually by meristem tip cuttings in May, 2012 in Gainesville, Fla., and has remained true-to-type since that time.

‘UF12-82-3’ has not been made publicly available more than one year prior to the filing date of this application.

When ‘UF12-82-3’ is compared to the female parent ‘UF11-73-8’, both plants have lance-shaped leaves, however ‘UF12-82-3’ leaves are deeper maroon in color, while ‘UF11-73-8’ leaves are more orange-red with lemon yellow margins. In addition, ‘UF12-82-3’ has a more vigorous, lateral, and spreading growth form than ‘UF11-73-8’.

When ‘UF12-82-3’ is compared to the commercial cultivar ‘UF08-19-10’ (U.S. patent application Ser. No. 14/120,608), both plants have lance-shaped leaves and a well-branched, mounded habit, however ‘UF08-19-10’ has a red streak through the mid-vein of the leaves, progressing to maroon, then emerald green at the leaf margin, while ‘UF12-82-3’ does not have a red streak through the mid-vein.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of ‘UF12-82-3’ when grown under normal horticultural practices in Gainesville, Fla. ‘UF12-82-3’ has a combination of novel mounded growth habit, excellent heat tolerance, and lance-shaped leaves consistently colored deep maroon with bright green margins that is significantly different than other coleus plants. It has superior stability in foliage color in both sun and shade conditions, maintaining stable color in all conditions. It has a vigorous but compact spreading growth habit with excellent lateral branching when grown as a stock plant, thus providing ample vegetative propagules for producers. This plant is desirable for long-season performance in the landscape.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘UF12-82-3’. The detailed description was obtained using twelve-week old plants grown in March-May, 2014 in a glass greenhouse in Gainesville, Fla. The plants were pinched 4 weeks after cuttings were rooted, then grown in 1-gallon pots for approximately 8 weeks. Color references are to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.), 2007 5th Edition.
